Product Argumentation
Rope Drive Design
Tilted sheaves True vertical lift No lateral hook drift Large drum diameter High-strength flexible wire ropes Single drum configuration
BENEFITS
Less wear on rope and rope guide Extended life time for rope Optimal usage of available space Avoids heavy twin hoists Savings in ownership
Product Argumentation
Rope Guide
Full wrap cast iron ring Proper rope guidance Avoids dangerous slack rope situations Tolerates side pulling
BENEFITS
Increased safety Economical guidance of ropes on drum Extended rope life time Savings in ownership
Product Argumentation
Central Lubrication
Easy and fast access to lubrication points Lubrication process save, no point will be forgotten
BENEFITS
Less downtime Lower maintanance costs Safe Savings in ownership
Product Argumentation
Hoist Motor
ONE inverter motor, no micro motors Closed loop with Encoder Only one size per hoist frame o 44kW CT17 o 60kW CT18 o 94kW CT19 and CT20 Temperature monitoring Fan cooled, CT19/20 with external fan
BENEFITS
Very slow speed for precise handling Fast lifting speeds for high productivity Less maintenance and wearing parts (no micro motors) Jogging and inching are avoided
Product Argumentation
Hoisting Brake
Magnetic dics brake Hoist duty lifetime rating High brake torque, 200% Fully enclosed, IP 66 No adjustment needed Minor wear, holding brake!
BENEFITS
High safety Extended brake lifetime Less maintenance costs Savings in ownership
Product Argumentation
Gear Box
Oil lubricated Grinded helical gear wheels Only one size per hoist frame o 1:82 CT17 o 1:105 CT18 o 1:128 CT19 o 1:524 CT20 • • •
BENEFITS
• Long lifetime due to high accuracy manufactuting Less downtime Less maintenance cost Less different spare parts, less different training efforts
Product Argumentation
Limit Switch
Geared upper and lower limit switch Four full adjustable switching points Hook block operated upper limit switch
BENEFITS
Increased reliability and safety No mechanicle wearing parts No damages to hoist structure in case of damaged gear limit switch
Product Argumentation
Controls
Set cubicles with readily configured controls Space for additions (bridge inverters) Horn 108 dB Lightning in every panel 230V 10A socket outside and inside PLIOTEX wire marking Special flat-cable entry Cubicles 1,5m/1m/0,4m with 2 doors
BENEFITS
Easy and effecient integration into crane system Fast and easy access Easy maintenance
Product Argumentation
Overload Protection
Overload protection by strain gauge sensor Measures rope force at pulleys Cuts hoisting if force exceeds maximum pre-set limit
BENEFITS
Protects hoist, crane and buidling structure from overloads Increased safety at work
Product Argumentation
Condition Monitoring
NovaMaster as standard Overload supervision Brake slippage and locked brake monitoring Thermal motor protection SWP counter Tandem hoist sychronisation optional
BENEFITS
Enhanced safety at work Optimized service intervals Lower downtime and cost of owner ship Indentification of miss-use
Product Argumentation
Dimensions
Compact track gauge Compact wheel base Low headroom, top of rail to top of hoist Equal wheel loads distribution, due to true vertical lift
„It‘s a winch“, as opposed to a package hoist
-
BENEFITS
Optimal usage of space Safe operation, no side pulling at runway end required Lower investment in steel work Longer lifetime, high availability Investment savings

Solutions
Hoist Tandem Control CAN-bus
- Standard, NovaMaster Tandem: • Electronic monitoring of safe tandem operation of two hoist • Signal transmission between hoists via BUS cable • Load summarization and crane overload - Options: • Anti collision device • LED load display, Sum load • Lifting speed synchronization via inverter of two or more hoist motors on common crane

Solutions
Crane Tandem Control
- Electronic monitoring of safe tandem operation of long loads by two cranes - Signal transmission between cranes via advanced radio controls - Anti-collision via photo-cells and reflectors - Matches the requirements of performance level “c” as per EN 13849 - Most comprehensive monitoring of crane conditions on tandem controls in the industry - Highest safety standard in the industry

Solutions
Anti Sway Control
Trolley + bridge inverter Height measure unit - Avoids harmful load peaks. Mechanical stress in electrical and mechanical parts is reduced (less maintenance) - Crane is easy to operate with optimal crane movements Operator’s focus is in controlling the load movement and not the hoist or crane movement - Time is not lost in increased load swing and extended time to place the loads and the load handling is more efficient Indication LED light Sway ON/OFF Encoder at rotating limit switch

Solutions
Main and Auxilary Hoist
- Every combination up to 160t possible • Two similar hoist • Two different hoist • Different speeds or height of lift - Hoist tandem control via NovaMaster is allways included - Controll methods can be: • V2 - only hoist A or B • V3 - hoist A, or B, or A+B together - Options: • Cable reel • Service platforms, one or both sides • LED load display • …
